    Rotary dryer working principle and specifications-Palet

    May 16, 2020 The rotary dryer’s drum is a slightly angled and rotatable cylinder with wet material entering from one end up and dry material collecting from the other end down. Hot air enters at the inlet or outlet end and exits at the top of the other end. The barrel is equipped with a forward-running plate, which makes the material to be continuously run up and down in the process of turning the barrel

    An 18’ dryer drum is not the only option. Rotary dryer drums as small as 4’ diameter can evaporate anywhere from 200 – 500-lbs/hr. Rotary drums much smaller than this have efficiency losses so an alternate drying system may be more beneficial. Using the same example above, with a product at 50% mcwb, a small rotary drum dryer can take
